Google Maps Marker disappearing after dropping - google-maps

I am trying to mark some spots on a google map. I am using google maps places javascript api.
function initialize() {
var mapProp = {
center: new google.maps.LatLng(userlatitude, userlongitude),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
//var map = new google.maps.Map(document.getElementById("map_canvas"), mapProp);
map = new google.maps.Map(document.getElementById("midsection"), mapProp);
var mapPosition = new google.maps.LatLng(-20.997110, 123.375544);
markers.push(new google.maps.Marker({
position: {
lat: -20.014006,
lng: 123.421746
},
map: map,
title: 'Mow my lawn',
animation: google.maps.Animation.DROP
}));
(if the Long/Lat are invalid, its because I randomly changed it for the purpose of this post)
I can see the marker drop down and bounce once. But then it disappears. I have tried setting the Zindex, changing the display and position type of the div canvas. But nothing I do seems to make the marker stay.

The problem ended up being hidden in my CSS.
it was just a Canvas: display:none call

Google Maps initial location

Hello guys I've got a simple question to ask, when I open my map I have set the lat and long to open some coords, then I place one marker with a infoBubble opening when the map is loaded, but after that the map opens in the maker position. I dont want that .. is it possible force the start location to open my map in the start position instead of the marker position?
thanks
function init() {
var mapCenter = new google.maps.LatLng(-8.799445,-63.922042);
map = new google.maps.Map( document.getElementById('map'), {
zoom: 17,
center: mapCenter,
mapTypeId: google.maps.MapTypeId.SATELLITE
});
var myLatLng = new google.maps.LatLng(-8.802732,-63.921939);
var marker = new google.maps.Marker({ map: map,
position: myLatLng,
draggable: true,
icon: icon
});
}
By default the API when a InfoWindow will be opened tries to pan the map so that the infoWindow is fully visible.
Set the disableAutoPan-property of the infoWindow to true to avoid this.

Change pin label in google maps?

How can I change the label for pins in an embedded google maps?
Ive figured out how to change the marker to my icon, but I need to restyle the A, B, C etc similar to how travelodge do for there map http://www.travelodge.co.uk/hotels/book/edinburgh-hotels
UPDATE this is the code that successfully uses a custom marker:
function addMarker(latlng, myTitle) {
markers.push(new google.maps.Marker({
position: latlng,
map: map,
title: myTitle,
icon: "www.linkto/myPin.png"
}));
}
Ive included markerwithlabel.js However this doesn't create any markers at all:
function addMarker(latlng, myTitle) {
markers.push(new MarkerWithLabel({
position: latlng,
map: map,
title: myTitle,
icon: "www.linkto/myPin.png",
labelContent: "$425K",
labelAnchor: new google.maps.Point(22, 0),
labelClass: "labels",
labelStyle: {opacity: 0.75}
}));
}
This is the code I was tying to adapt:
http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerwithlabel/1.1.8/examples/basic.html
If you managed to change the marker icon, then you did all the work.
A marker does not have a label. What travelodge does is that it has markers for each letter and then sets them according to the search results.
EDIT:
It seems there's a special library to do what you want (go to "Styled Marker"):
http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries#MarkerWithLabel
To see the code click in "Development versions", then "Examples" and then look at the source code of the pages. Here's the Simple example code:
function initialize() {
var myLatLng = new google.maps.LatLng(37.313477473067, -121.880502070713);
var myOptions = {
zoom: 11,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.SATELLITE
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
var styleMaker2 = new StyledMarker({styleIcon:new StyledIcon(StyledIconTypes.BUBBLE,{color:"ff0000",text:"I'm a marker!"}),position:new google.maps.LatLng(37.383477473067, -121.880502070713),map:map});
var styleMaker1 = new StyledMarker({styleIcon:new StyledIcon(StyledIconTypes.MARKER,{color:"00ff00",text:"A"}),position:myLatLng,map:map});
var styleMaker3 = new StyledMarker({styleIcon:new StyledIcon(StyledIconTypes.MARKER,{color:"0000ff"}),position:new google.maps.LatLng(37.263477473067, -121.880502070713),map:map});
}

Google Map not showing up API V3 or showing up very slowly

I'm having a heck of a time trying to get a basic Google Map to show up. I've been on Stack Overflow for hours and haven't had any success so far. The closest I've gotten is the map loads 1/4 of a square, the top left quarter. But then if you try to drag, zoom, etc it just turns grey like the rest of the map. On a few occasions, with the same code, the map will load fully but only after a long time (not sure exactly how long, but > 5 minutes).
In my template I have
<div id="map" style="width: 500px; height: 400px;"></div>
And then in my backbone view
$.getScript('http://maps.google.com/maps/api/js?sensor=false&callback=gMapsCallback')
window.gMapsCallback = function(){
var myLatlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
}
Any ideas what might be happening? I am also open to any suggestions on a superior way to load a google map into a backbone view.
Ok, turns out there were a number of issues, including embedding a map in a Bootstrap tab, not including a callback, defining the div height and width, setting a small delay to load the map, and setting css attributes for the map. Oi. My final solution turned out to be:
In the template
<script src='http://maps.google.com/maps/api/js?sensor=false&callback=gMapsCallback'></script>
<div id="map" style="width: 500px; height: 400px;"></div>
In the stylesheet
#map img {
max-width: none;
}
#map label {
width: auto; display:inline;
}
In the Backbone View
setTimeout(function(){
var myLatlng = new google.maps.LatLng(53.1, -2.44);
var mapOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
// Create marker
var marker = new google.maps.Marker({
map: map,
position: new google.maps.LatLng(53.1, -2.44),
title: 'The armpit of Cheshire'
});
// Add circle overlay and bind to marker
var circle = new google.maps.Circle({
map: map,
radius: 10000, // metres
fillColor: '#AA0000'
});
circle.bindTo('center', marker, 'position');
google.maps.event.trigger(map, "resize");
map.setZoom( map.getZoom() );
}, 100);
Painful. Notice that when I call the gmaps script I had to include the callback even though I never use it. Without it, it didn't work fully. No clue why.

Google Maps click to drag not working

I'm using this super basic code to add a google maps to my site:
var map;
function initMaps(latIn, longIn, htmltext) {
var LatLng = new google.maps.LatLng(latIn, longIn);
var Options = {
zoom: 13,
center: LatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("mapStatic"), Options);
marker = new google.maps.Marker({
position: LatLng,
map: map
});
marker.setMap(map);
map.enableDragging();
}
google.maps.event.addDomListener(window, "load", initMaps);
The map is displaying fine, but for some reason I can't drag it around, is it possible that some other piece of javascript is doing this?
I look around, but didn't find anything that could cause a problem.

Google Map not re-drawing after clicking a line

My Google Map only shows up fine the first time. Clicking the line a second time or more, the map does not re-draw properly and so is unusable.
I am using the following code:
var myLatlng = new google.maps.LatLng(53.3820845337596, -1.46965489864111);
var myOptions = {
zoom: 15,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
scrollwheel:false
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'we are right here ...'
});
var myLatlng2 = new google.maps.LatLng(53.3820845337596, -1.46965489864111);
marker.setMap(map);
google.maps.event.addListener(marker, 'click', function(){
infowindow.open(map, marker);
});
google.maps.event.trigger(map, 'resize');
With google.maps.event.trigger(map, 'resize') at the end being my attempt to get the map to behave correctly.
You can see the effect at http://test2omniforce.co.uk/node/8 and clicking on the map image.
It doesn't look like a width and height are set on your div with id 'map_canvas' in map.php. I wonder if this is causing the map to not render correctly?
Maybe try adding some dimensions and see if that works.
Good luck!
